SAFETY DEVICE FOR WRINGERS.

Specification of Letters Patent.

Application tiled December 28, 1911. Serial N 0. 668,362.

T 0 all whom it may concern:

Be it known that I, FRANCIS T. JOHNSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Safety Devices forVVringers, of which the following is a specification. v

My invention relates to means for releasing the rolls of wringersinemergency' cases, and has for its object to provide a A, A are thevertical side bars of the,

wringer, B, B the rolls and C a cross bar which is placed loosely in thespace between the two portions of the vertical side bars. Between thecross bar and the upper roll is disposed the tension springs D D.

E E are U-shaped clips which attach by a cross bolt E to a block Esecured by the screws E to the side bars. bolt F in the upper part ofeach clip is preferably provided with a roller F which-bears upon theupper surface of the outer. end of the cross bar C.

G Gare links pivoted together at G and each notched at G so as to engageeach the' upper portion of one clip. The pin J,

.which pivotally connects the two links G G,

is adapted to slide in a'slot J in a standard J which rises from thecross bar C. On one end of the pin is downwardly depending bar J 3 witha handle J and on the other end of the pin isa cord J 5 adapted to runover pulleys J J on the cross bar. Thence it descends and is attached tothe lever- K, which projects :from the fulcrum K? and terminates in thefoot piece Kt. 1 I

Itwill be understood that these devices thus described are illustratedmore or less diagrammatically. The object isto' show one way. in whichmy invention can be car-f ried out and applied to a wringer.

A transverse Great modifications of the device could be made withoutdeparting from the spiritof my invention.

The use and operation of the invention is as follows: Assuming that thedevice has been applied, .the wringer will have the appearancesubstantially as indicated in Fig.

1, and the two wring'er rolls will be forced together by the spiralsprings in the usual manner. In the meantime there is available andWithin easy reach in front of the operator either the handle or the cordleading to the foot lever. If the operator should get his hand betweenthe wringer rolls'or some emergency should arise which would call forimmediate release of the pressure which forces the two rolls together,the operator can either b pressing upon the foot lever or the hand e Jdraw down the two links and thus spread their ends. This action willimmediately force the two clips outclip rollers which move along thesurface of the ends of the cross-bar. The cross-bar Patented Apr, 8,1913.

ywardly, the action being facilitated by the being otherwisedisconnected, is immediately prising a frame, a cross-bar, springsbetween the bar and the rolls, clips pivoted on the frame adapted tooverhang the ends of the cross-bar and means for pushing the clipsoutwardly to disenga e the same and release the cross-bar, said 0 ipspivoted to blocks projecting ,from the side surface of the frame. i

3. A safetydevicefor wringer rolls comprising a frame, a crossebar,springs between I the bar and the rolls,clips pivoted on the frameadapted to overhang the ends of the J cross-bar and means for pushingthe clips outwardly to disengage the same and release the'cross-ba'r,said disengaging means com-' prising laterally pushing parts.

' A safety devlce for wringer rolls comprising aframe, a cross-bar,springs between the bar and the rolls, clips ivoted on the frame adaptedto overhang t e ends of the cross-bar, and means for pushing the clipsoutwardly to disengage the same and release the cross-bar, saiddisengagin means comprising toggle bars whose ends engage the clips andmeans for depressing the other ends of theto-ggle bars. I

5. A safety device for .wringer rolls comprising a frame, a cross-bar,springs between the bar and the rolls, two holding devices for holdingthe cross-car to the frame and links pivotally secured together abovethe cross-bar their ends abutting the two holding devices and means forpulling the ends of the links down to disengage the holding devices.

6. A safety device for wringer rolls comprising a frame, a cross-bar,springs between the rolls and the ends of the cross-bar, clips pivotedto the frame and overhanging the ends of the cross-bar, toggle barspivoted together above the crossbar and adapted to abut the clips andmeans for pulling the inner ends of the toggle bars down to spread 25the bars and disengage the clips.
